ribs, the float and the brushoperate in a` certain relation to one another. vThe saws, when new,

have a diameter usually of 121/2 inches-'WAS they are resharpened from time to timetheir diameter is, of course, reduced;` themetal beingcut away` or otherwise removed by the resharp'ening;andiV the reduction `of the diameter from'` such cause l' maybe carried` as far as two inchesorfslightly more. Obviously wthsuch reduction `in thedi-` ameter of the saws,.the relation among the parts mentioned, that is to say the saws, ribs, lfloat and brush, is varied andsuch variation, unless .suit-" l ably corrected or compensated, impairs the cp-l eration of the linter. Heretofore, it has been pro' posed to effect this correction or compensationtby' separate manual `adjustmentsof theshafts of the saws, iioat and brush. Thushthe rshaft or mandrel of the gang of saws `hasbeen'shirnmed `up or otherwise raised, thexbreastin whichfthe` iioat ismounted has beenloweredandthe shaft of the `'brush `has been shifted laterally `in'corinection with necessary adjustments of the posi.`

The objection to this proceeding isjthat it requires,

a veryserious outlayv of time andlabor and does not necessarily maintain the efficient working re# 'l i 'f slighttolerance either way., The `adjustmentsof which,` of course; is estab--` lished at thestart of the operation of the linter; is one wherein' the brushwhas-fa" suitalalesrunav lation ofl theparts. i r This eicient relation,

tain the proper working relation of the saws. Certain features of the invention are, therefore, also applicable to gins and with the purposes and advantages described.

. With the above objects and characteristics in view the invention consists generally in novel features of construction, combinationand relation which will be pointed out in detail as theV description proceeds. y 'Y An embodiment of the invention is illustrated in the accompanying drawings, in which:

lFigure 101 is 'a detail plane View, somewhat enlarged showing a scale and (Jo-operating pointer for: indicating the adjustment of the machinewith reference to variations. in saw diameters. Theiinter shown in the accompanying drawings isV of-a well known type andits details, such asA thewind and division plates, the mote board,fea-' tures connected therewith and otherdeta-ils p'ossessing no novelty will require no specific descrip-f tion, being at once apparent to those skilledin thel art.

rThe' parts in connection with which the presi ent improvements are applied are the saws 1 I hinged' as' at 1l to a frame bar 12Y whereby the breast may be raised from its operative position to. permitf a gang of saws to be set in or removed from operative position.

respect lto the above structural details we have thus far described nothing new.

The linter frame includes end standards 13' whichsupport the bearings 14 for the saw mandrel 2 and the bearings 15 for the brush shaft 4.

The saw mandrel 2 is, in present typesfof linters,

originally centered horizontally or substantiallyv so with relation to the brush shaft fi and, according'i to: the invention, is adjustable,v as a center, along a radial path inclined upward and inward atan: angle to the horizontal of the order of For the purposeof such adjustment the bearings 14 are mounted upon sup- 'litt y porting, blocks 16 in; turn supported on the upper bars 17 of the standard 13` and those .parts 17a of such bars onl which the blocks 16 rest are -utilized as guide rails along which said blocks may be' moved `to effect the'adjustment of the saw mandrel along the described radial path. Hence the rails 17ahave an inward-and upward inclinaclined in Vconformity tion lconforming to-said radial path and the lower to said rails whereby said blocks in any position thereof will have stable support on said rails and will be readily movable upward along the same. To aid in holdingthe blocks 16 in the positions to which they may be adjusted each rail 17a may be formed with a longitudinal slot 17D to accommodate cap screws 18, the Shanks of which are engaged in threaded sockets 19 provided with or formed on the inclined base of each block 16 and the caps of which engage frictionally against the under side of the upper flange of the rails. It is also preferred to provide along the upper face of each rail a longitudinal recess 17e and to provide the base of each block 16 with a longitudinal rib 16a for engagement in the recess 17C of the companion rail, the recesses 17e and the ribs 16a cooperating in positively guiding the blocks 16 along the rails.

When adjustmentof the blocks 16 is required the screws 18 are loosened in order that said blocks may be freely movable alongvthe rails 17a and when said blocks havebeen moved to the .position -desired said screws are then tightened in order to secure or aid in securing the blocks in such position..

The mechanism'r for effecting the movement of the blocks 16? along the rails 17a and the resultant adjustmentof the position of the saw mandrel preferably andconveniently includes screw operated wedges 20 having vertical. inclined or cam engaging faces21.` 'Ihe wedges 20 directly cooperate.l with lugs 22 formed or provided on the blocks 16v and their-cam faces 21 bear against conforming cam faces 23 on'said lugs. The wedges 20 and 1ugs22 are so arranged relatively. to one another that inward movementof said wedges, that is to say movement of Vsaid wedges toward oneanother, will` effect upward movement of the blocks 16v along. thev rails 17a. Such movements of the wedges 20 are effected by aA transverse shaft 24 having at or near its respective opposite ends right andleft hand threads 25, one set of threads for each wedge. The wedges are formed or providedwithv nuts26 forengagement with the respective sets of threads 25. As shown the nuts 26 project downward from said wedges and the bar 17 is formed adjacent the lower ends of the rails 17a with recessesy 2'7which provide clearances for the nuts 26. The wedges 20 may react against any appropriate parts. For this purpose the adjacent vertical legs 28 of the standards 13 may be utilized to take the thrust of said wedges. The legs 28 are preferably each provided at their upper ends with horizontal recesses 29 andthe wedges are provided with` guide` ribs 30l for engagement inl said-recesses. The shaft 24 is suitably journalled bearings incorporated with or mounted on bars of the linter frame and projects beyond said frame at one end, its projecting portion being provided with a handwheel 31- by'which said shaft may berotated in order to effect the movement ofthe Vwedges 20 rand the`resultant movement of the blocks 16, thereby to adjust the position of the saw mandrel.

. When the saw mandrel is thus adjusted it is in most cases necessary or desirable to efect a conforming adjustment-of the linter' breast in order that the proper clearance between the peripheries ofthe saws 1 and the oat 7 and also the. proper relative location of the ginning point (i. e` the point at which the saw teeth after passing beyond the float pass between the ribs 8) maybe maintained. For 'this phase of the adjustment the hinge-'connectionsll may be uti- 1ized. Thelinterbreast, addition to the hinge GOv i connections 11, has supportifrorn `a transverse.A shaft24 has"looselymountedlthereon: a pinion frame bar 32 which I may 1' 'extend i betweeni .1 and:

g be `secured to `the legs: 28` ofthe standard @13.`

`'I'he supportingelements for the breast may con-4 `sistof posts 33 carried by theframe bar v32 and"` whichproject at a suitable angle upward -and outward from said bar, ythe lower rib'rail 10` Y resting; against the` upper. ends of fsaidfposts,

" two of whichdarefpreferably employed, one lo.

cated somewhat near each end of thefraine bar 32.` AThe posts'33iare adjustable in ,the direction of their axeslinorder` toprovide for raising `,or

` f cally in connection with the: operation of Vfthe openings said bar carries plates 35wwhich are mounted for sliding movement lengthwise of `said bar or transversely of` theflinter."` The plates 35 are directly supported by stationary frames4 36 whose bars x outline .rectangular openings" 37';

` to the movement of the l'wedges` 20 wherebythe` shaft 24 to effect the movementsof the wedges 20.

. Thebar 32 is `formed withopenings 34 through" which the posts 33.extend and by which they are guided and laterally supported. Behind said the framesl36 being suitably secured to thebar 32. The upper'and lower bars of `each frame 36 are rabbeted along .their inner faces to. provide shoulders 38 by which the plates 35 arefsupported andjguided. The plates 35'are formedwithangular extensions 39 i which fproject through vthe openings 3'71and have bottom anges 40 so. formed thatithey are operative ascams in controlling the movements of the fposts 335-1 4The'iilanges 40 in their transverse direction `have ya suitable angle to the horizontal .which is conformableto the angle at which the posts 33 extend and in their` `longitudinal direction lare inclined inwardand upward-and at an angle ywhich will provide for the movement of said posts ata rate co-ordinated adjustment of the position of thefoat will always y be` proportionate to lor ico-ordinated with'the adi justment of the position of the saw mandrel.

' plates 35.`

i The flanges 40 of the `respectiveplates.35 preferably extend inwardly andupwardly in relatively opposite directions'` 4in orderf'that the lateral f stresses incident tojthe` thrusts whichthey Vtake maybe balanced ors'opposedr.. l

The plates 35are preferablyoperated similarly to the wedges 20,. that ris `tofsayvby `means' of a transverse shaft 41farrangedabove andparallel I i to the shaft 24 and having` oppositely threaded portions 42 for co-operation with the respective are` provided with depending` nuts43 for engages i ment with the respective oppositely threadedpor-v as the shaft 41 isrotatedthefplatesz 35willbe moved in'opposite directions and according to` tions of the shaft .'41,` It will be apparent that their directions of movementwillraise or permit the lowering by gravity of the 1 supporting posts '33 with corresponding movements of .the breast about the hinges 11. Thus when the saw mandrelv is adjusted upwardly and inwardly thefbreast is proportionately lowered;

j The shaft 41 is preferably operated` `frornthe` shaft 241through connections which,.1however,

may be regulated to permit independent operation of either of said shafts. Thus the. shaftV 'f 41 at one end projects througha clearance open-` ing 41a in one of :the lugs V26 and its projecting portion has .fast thereonl a. pinion 45` andthe The" extensions 39 `01:...the` plates 35V 44` which meshes` with the pinion'45`, :said pinions being enclosed ina suitable housingy46 through and beyond whichsaid shafts project. s The shaft 24 carries adjacentlth'e `hand `wheel 31a slidably keyed clutch'element 4'7 havingprojections 48 for engagement in recesses in the hub of the pinion` 44, the adjacentwall]` of the `casing 46` s having antopening `througlfrwhich the end of the,` clutcheelement may pass.` '3 When theclutch element 4'7` is .iengagedwith thewpinion 44said pinion1will,of course,4 rotate with 4the shaft.` 24` and through the pinion 45 will operate the shaft 41. When the Vclutch element 47 is disengagedfrorn :thepinion 44 the. latter will be free" on the shaft' 24 and hencef-saidushaft.- may be rotatedless than the maximum'` lint capacity ofthernal-r chine or may desire to operate "withless iexpend-4` iture of power.' Such regulation of the quantity of lint produced by the machineor the limitation of thevpower'requiredffor its operation canbe had by Varying the clearance between the saws `and the float. Hence the provision for thepermissible operation ofthe shafts 24 and 41 inde' pendently of one anotherprovides for such vari-i ation in the clearance between thesaws. and the oat'andfit follcwsthat the clearance may initially be regulatedas desired Aand thereafter automaticallyv maintained in vconnection .with the vad` justment ofthe Isawswby` causing the'shaftV 41 `to be rotatedfrom theshafti2`4:` Y f The required 'extent of the adjustment of th sawm'andrel in a particular caseicanbe determined bythe number of turns of` the shaft'f24 aseiected by the` handwheel 31." However, it is preferable to provide suitable means for indicating the `position of` the 'saw mandrel with referenceyto saws of any given diameter within therange of adjustment:` `A convenient mecha@ nism for thispurposefconsists 1or" a rack` bar 50 mountedontheupper face ofone of the wedges s 20 and engages a toothed` sectorll provided as a tail piece'on the pointer 52` pivotally mounted onthe ,upper face of the adjacent leg 28, the

end of the lpointer traversing a 4scale 53 which is suitably calibrated with indicationsof the saw diameters, these calibrationsbeing shown in the drawings in degrees of 1/8 of an inch for diameters from amaximum of 121/2 inches to a minimum of "11 inches.A

eters may be used and the calibrations of the scale53 maybe extended accordingly.

Theuse of the linter will ordinarily beistarted withsawsuof maximum diameter, the standard maximum being` 121/2 inches." As these arere Aduced in" diameter by repeated sharpening their center, i. e. thesaw mandrel, must be set nearer,

the brush inorder that the proper running clearance may )be maintained. This adjustment is effected by'the unisonous vmovement of "the wedges 20 in the manner described. Since the maximum or other determined clearance between the sawsand the `float must in all cases be maintainedinorder to insure the continued eiiicient operation of 4-the linter, the saws and the float` must `also berelatively adjusted in connection with the relative adjustment-of the saws and the If the construction of the linter is otherwise suitable, saws of smaller diambrush. Therrelative adjustmentof the sawsiand,

ythe float' isl effected by :lowering thetbreast, this operationv being vaccomplished by the: unisonous movement ofthe-slide p1ates35 in directionssuch; that the posts 33 ride relativelydownward along. the cams provided bythe langeslfof'the slide. plate extensions 39. Y i: While the two adjiistmentscould; of course, beV effected separately, they are preferably-'effected in the; manner described,A that is.. tol say' by operatingv the vshaft lll'frorn the shaft 24 whereby the .unisonous movement; of the slide plates' 35 visso synchronized with the unisonous'movements of thecams ZOthatthe'adjustment of the float will at allrtimes be exactly proportionateto and substantial ,alteration ofv theginning point.. The. inclined path along which vthe saw .mandrel is` adjusted moreover insures the proper tangential.E relation at all-,times of theV saws to thefbrush j andfpermits of thelowering of the'breast-about,

its hinges 1l to effect the adjustment ofthe float without any interference between the'saws and the upper andv lovverrib rrails. Since allv adjustments maybe effected simultaneously,` accurately andL in' yco-ordinated relation simply by turningthe hand wheel 3lA with resultant rotation ofthe shafts 24 and lllthey require only'4 negligible effort and may' bercompletedin 'a'.few, moments of time, the movingv pointer, 52 by itscoincidence with the -scale rmarking correspondingjtorthe diameter of the particular saws being available to indicate when the adjustment has been' completedf AIngmaking vthese adjustments .to compensate for changes from saws of greater diam,` eter to saws' of less diameter the saws may be: set in position either before or after theadjustment is made. rThe breast may of coursegbe swungback onv4 its hinges while the'adjustlrnents are being made and lowered after they' have been completed, its position in any case being controlled by the-posts 33 as held by and upon the" cam flanges 40.` f

Assuming that the saws of a gang to beput into thelinter are of greater diameter than the saws of a gang just previously used,the' saws and thev float are adjusted in the manner describedbut inA opposite directions, that is tosay the shaft 24 is rotated to move the cams 20 outward and permit the blockswll andibearings 14 attached' thereto to slide downward along' the rails 17a and the shaft 41 isrotated to effect such movement of the slide plates 35 as will cause' theirv cam flanges 40 tomove the posts 33T outward,

' thereby to support the ibreast at a higher elevation. Such adjustments having been-made the gang of sawsvof greater diameterfmay be set in position and the breast lowered to the position'v determined by the posts 33 asj held by and upon the cam flanges 40. y

vIt will, of course, be apparent that `,the time from the operation `of the linter lost-in consequence rof the adjustments ydescribed is almost negligible vand hence that lthe production icavpacityof the linter, based "onthe: time of. its opigesaeoi;

eration', is effectively:4 increased,l this. marked economy.A being` obtainedlalong with anl advantageous economy of labor. since but a few moments oftime of but a singley operator is all that isA required, no adjustment Vof anyof the 'other parts, i'. e. division and wind plates and mote board, being necessary. i
